DETAILED DSECRIPTION OF THE EMBODIMENT

[0024] Preferred embodiments of this invention will be described with reference to the accompanying drawings:

[0025] (1) Whole Structure of Information Processing System

[0026] In FIG. 1, a reference numeral 1 shows an information processing system which comprises a notebook personal computer and a digital portable telephone 3. And the notebook personal computer 2 and the digital portable telephone 3 can perform communication with each other by a radio communication method based on a radio communication standard called the Bluetooth (trademark).

[0027] Note that, the Bluetooth is the radio data communication standard for short distance standardized by the Bluetooth special interest group (SIG) which is a standardizing group, in which 79 channels each having a bandwidth of 1 MHz are set within the industrial scientific medical (ISM) of 2.4 GHz bandwidth, a spread spectrum communication method utilizing a frequency hopping method which switches channels 1600 times per one second is used to perform data communication within 10 m at data transmission rate of 1 Mbit/sec (actual rate of 721 kbit/sec).

[0028] (1-1) Structure of Personal Computer

[0029] As shown in FIG. 2, the notebook personal computer 2 has such a structure that a random access memory (RAM) 11, a display 12 that is a liquid crystal display, a keyboard 13, a hard disk drive (HDD) 14, a power control unit 15, a radio interface for short distance 16 based on the Bluetooth standard, a touch pad 17 and a jog dial 18 are connected to each other with a data bus BUS, so as to communicate various data between these units through the data bus BUS.

[0030] Note that, the jog dial 18 is formed on the side surface of the notebook personal computer 2 as an operation means which is capable of easily carrying out system setting and various functions of various application software through rotation operation and pushing operation.

[0031] The HDD 14 stores various kinds of programs including an operating system program such as the Windows 98 (trademark of Microsoft corp.) and a jog dial utility program, and various kinds of personal information databases.

[0032] The CPU 10 takes out various programs stored in the HDD 14 when necessary, opens and executes them on the RAM 11 to control each unit, thereby performing various processing, and it displays the processing results on the display 12.

[0033] When the notebook personal computer 2 is driven, the CPU 10 opens the jog dial utility program as well as an operating system program, on the RAM 11.

[0034] Thereby the CPU 10 displays, for example, a jog dial window 50 shown in FIG. 3 on the display 12, and at the same time virtually displays the contents of the rotation operation and the pushing operation of the jog dial 18 on the jog dial window 50, to show a user an operated situation.

[0035] That is, when the jog dial 18 is rotated, the CPU 10 rotatably displays main menu items 51 in accordance with the rotation operation on the jog dial window 50, and on the other hand when the jog dial 18 is pushed the CPU 10 determines the item being selected by a selector (inverse color part) 52 and executes the processing corresponding to the item.

[0036] The power control unit 15 controls the power supply to each unit of the notebook personal computer 2, and always supplies power to only the radio interface for short distance 16 even when the notebook personal computer 2 is in an inactive mode (that is, in a sleep mode), so it is always active even the notebook personal computer 2 is in an inactive mode.

[0037] When the notebook personal computer 2 receives a driving signal from the digital portable telephone 3 via the radio interface for short distance 16, it outputs a driving command to the power control unit 15 even in an inactive mode, to reactive.

[0038] Such a notebook personal computer 2 previously stores an identification ID used for judging whether a digital portable telephone 3 is owned by a proper user of the notebook personal computer 2, in order to prevent the remote control by a digital portable telephone 3 owned by a third party.

[0039] Further, the notebook personal computer 2 previously sets items which can be remotely operated with the digital portable telephone 3 out of the main menu items 51 of the jog dial window 50 displayed on the display 12, so as to perform processing corresponding to the set items.

[0040] In actual, in the case of setting items, the user rotates the jog dial 18 so as to place the selector 52 on a detailed setting item 51D out of the main menu items 51 on the jog dial window 50 (FIG. 3), and then pushes the jog dial 18.

[0041] Thereby, the notebook personal computer 2 displays on the display 12 an item setting screen 40 in which main menu items 71 Corresponding to the main menu item 51 of the jog dial window 50 (FIG. 3) is shown in a setting item display area AR1, as shown in FIG. 4A, and allows the user to set items to be transmitted to the digital portable telephone 3 using the determined item display area AR2.

[0042] The user performs setting using the jog dial 18 or a mouse pad 17 this time, and selects and then determines an E-mail item 71B and an address item 71F as items which can be remotely operated with the digital portable telephone 3, out of the main menu items 71 including a word processing unit item 71A, the Email item 71B, a game item 71C, a detailed setting item 71D, a browser activating item 71E, the address item 71F and a volume item 71G, displayed in the setting item display area AR1.

[0043] Then, the notebook personal computer 2 copies and displays the E-mail item 71B and the address item 71F in the determined item display area AR2 on the item setting screen 40 as shown in FIG. 4B, and operation of an end button 43 by the user terminates the setting processing for items to be transmitted to the digital portable telephone 3. Thereby the notebook personal computer 2 stores the setting contents of the set items in the HDD 14.

[0044] In this way, the notebook personal computer 2 previously stores the identification ID and the setting contents for items which can be remotely operated with the digital portable telephone 3, in the HDD 14, and performs radio data communication with a close digital portable telephone 3 (FIG. 1) which can be used in the Bluetooth, via the radio interface for short distance 16 and the antenna 18.

[0045] (1-2) Structure of Digital Portable Telephone

[0046] As shown in FIG. 5, in the digital portable telephone 3, an electronic erasable program read-only memory (EEEPROM) 21, a jog dial 4, a plurality of operation keys 22, a display 23 which is a liquid crystal display, a signal processing unit 24, and radio interface for short distance 25 based on the Bluetooth standard are connected to a CPU 20 for controlling the whole performance of the digital portable telephone 3, and a microphone 26, a speaker 27, a transmitter section 28 and a receiver section 29 are connected to the signal processing unit 24.

[0047] Note that, similarly to the jog dial 18 of the notebook personal computer 2 as described in FIG. 2, the jog dial 4 of the digital portable telephone 3 is an operation means for easily carrying out system setting and various functions in various application software by rotation operation and pushing operation.

[0048] Further, the EEPROM 21 stores various programs such as a jog dial state managing program, and personal information including an identification ID which is used to realize communication of various kinds of information with a notebook personal computer 2.

[0049] The CPU 20 takes out various programs stored in the EEPROM 21, when necessary, to control each unit, and thereby performs various processing, and then displays the processing results on the display 23 according to the processing.

[0050] When the digital portable telephone 3 is driven, the CPU 20 takes out the jog dial state managing program from the EEPROM 21 to detect an amount of change in rotation of the jog dial 4 by polling which is performed every 5 minutes and to always detect whether the jog dial 4 has been pushed.

[0051] Therefore, the CPU 20 displays various kinds of information (entered telephone numbers or menu items, or a calling history or a telephone directory, for example) corresponding to the command information entered through the jog dial 4 or the operation keys 22, on the display 23. Further, the CPU 20 controls the signal processing unit 24 in accordance with the command information entered through the jog dial 4 or the operation keys 22, to perform various kinds of processing according to the command information such as call processing and call ending processing.

[0052] In actual, the digital portable telephone 3 is a code division multiple access (CDMA) scheme cellular portable telephone under the direct sequence (DS) system based on the IS95 standards, and during conversation, the signal processing unit 24 performs error correction and then convolutional coding on an audio signal inputted vial the microphone 26, and then performs frequency diffusion by multiplying a pseude noise (PN) code, and modulates the resultant, in order to generate a transmission symbol stream which is then inputted to the transmitter section 28. The transmitter section 28 performs the digital/analog conversion on the transmission symbol stream to generate a transmission signal, then performs the frequency conversion processing and amplification processing on the transmission signal, then the resultant is outputted via the antenna 30.

[0053] On the other hand, the receiver section 29 performs the amplification processing and then the frequency conversion processing on the received signal received via the antenna 30, then performs the analog/digital conversion to generate a reception symbol stream which is then inputted to the signal processing unit 24. The signal processing unit 24 demodulates the reception symbol stream, then performs the back-diffusion by multiplying a PN code and furthermore, performs the maximum likelihood estimation processing using the convolutional code and then error detection processing in order to generate an audio signal which is then outputted to the speaker 27.

[0054] Further, the signal processing unit 24 transmits a control signal to the base station (not shown) via the transmitter section 28 and the antenna 30 to perform call processing and on the other hand, receives the call-arrival signal via the antenna 30 and the receiver section 29 and informs the CPU 20 of the call arrival.

[0055] The CPU 20 controls the signal processing unit 24, to perform radio data communication with another communication terminal connected to the public circuit via the transmitter section 28, the receiver section 29 and the antenna 30.

[0056] Note that, the digital portable telephone 3 may utilize the global system for mobile communication (GSM) system, or the time division multiple access (TDMA) scheme, in addition to the CDMA system and also may utilize the international mobile telecommunication system (IMT)-2000 system which is the next-generation cellular phone system.

[0057] By the way, the digital portable telephone 3 has a remote control start key which is included in the plurality of operation keys 22, and when the remote control start key is pressed, the signal processing unit 24 and the radio interface for short distance 25 exchange various kinds of communication data under the control of the CPU 20.

[0058] Therefore, the digital portable telephone 3 can perform radio data communication with a close notebook personal computer 2 (FIG. 1) which can be used in the Bluetooth, via the antenna 31.

[0059] (2) Remote Operation Processing

[0060] Next, FIG. 6 shows a sequence of remotely operating the notebook personal computer 2 with the digital portable telephone 3 in the information processing system 1.

[0061] As shown in FIG. 6, at step SP1 when the “remote control start key” is pressed, the CPU 20 of the digital portable telephone 3 generates a driving signal and also takes out an identification ID inherent to the digital portable telephone 3 from the EEPROM 21 and transmits them to the notebook personal computer 2 via the radio interface for short distance 24.

[0062] At step SP2, when the CPU 10 of the notebook personal computer 2 receives the driving signal from the digital portable telephone 3 via the radio interface for short distance 16, it starts in the case where it has been in an inactive mode, then takes out the identification ID (ID inherent to the previously registered digital portable telephone 3) stored in the HDD 14, and then judges whether it is identical to the identification ID received from the digital portable telephone 3.

[0063] Here, the CPU 10 of the notebook personal computer 2 compares the identification ID previously stored in the HDD 14 to the identification ID received from the digital portable telephone 3, and if the comparison result shows that they are not identical, it judges that the access has been improperly made by a third party which can not treat the various kinds of personal information stored in the HDD 14, and informs the digital portable telephone 3 which is a sender of the identification ID that the radio communication for short distance can not be accepted.

[0064] On the contrary, the CPU 10 of the notebook personal computer 2 compares the identification ID previously stored in the HDD 14 to the identification ID received from the digital portable telephone 3, and if the comparison result shows that they are identical, then it judges that the access has been properly made by a person which can treat various kinds of personal information stored in the HDD 14.

[0065] In this case, at step SP3 the CPU 10 of the notebook personal computer 2 generates item data D10 based on the setting contents (the E-mail item 71B and the address item 71E) set on the item setting screen 40 already described in FIG. 4, and then transmits it to the digital portable telephone 3 via the radio interface for short distance 16.

[0066] This time, the CPU 10 of the notebook personal computer 2 shifts the main menu items 51 so that the selector 52 is located on the E-mail item 51B out of the main menu items 51 on the jog dial window 50 as shown in FIG. 7A.

[0067] At step SP4, when the CPU 20 of the digital portable telephone 3 receives the item data D10 via the radio interface for short distance 25, it displays a menu screen 60 showing the E-mail item 61B and the address item 61F on the display 23 based on the received item data D10 as shown in FIG. 7B.

[0068] At this time, the CPU 20 of the digital portable telephone 3 places and displays the selector 62 shown by slant lines on the menu screen 60, on the E-mail item 61B, like the E-mail item 51B selected by the selector 52 on the jog dial window 50 of the notebook personal computer 2.

[0069] At step SP5 when the user rotates the jog dial 4 (FIG. 1), for example, by one click in the downward direction of the main case, the CPU 20 of the digital portable telephone 3 shifts and displays the selector 62 on the menu screen 60 by one item in the direction shown by the arrow A, as shown in FIG. 8A, and generates operation data D11 representing the operation contents (one-item shift in the direction shown by the arrow A) as well as generating select data D12 corresponding to the item name (address) being selected, and then transmits them to the notebook personal computer 2 via the radio interface for short distance 25.

[0070] At step SP6 when the CPU 10 of the notebook personal computer 2 receives the operation data D11 and the select data D12 via the radio interface for short distance 16, it shifts, based on the received operation data D11, the menu items 51 on the jog dial window 50 by one item in the direction shown by the arrow B, as shown in FIG. 8B.

[0071] At this time, the CPU 10 of the notebook personal computer 2 judges whether one-item shift in the direction shown by the arrow B makes the menu item name (“word processing unit” in this case) being selected by the selector 52 identical to the item name (that is, “address”) of the select data D12. At this time, when it is not identical to the item name (that is, “address”) of the select data D12, then the CPU 10 of the notebook personal computer 2 shifts the main menu items 51 on the jog dial window 50 in the direction shown by the arrow B until it is identical to the item name (that is, “address”) of the select data D12.

[0072] In this way, the same operation as the operation contents of the digital portable telephone 3 reflects on the jog dial window 50 of the notebook personal computer 2, as shown in FIGS. 9A and 9B.

[0073] As described above, the digital portable telephone 3 transmits the operation contents in the form of the operation data Dll and select data D12 every time when the jog dial 4 (FIG. 1) is operated, and the notebook personal computer 2 can execute the rotation display on the jog dial window 50, associated with operations of the digital potable telephone 3.

[0074] At step SP7 when the user pushes the jog dial 4 (FIG. 1) while the address item 51F is being selected (FIG. 9B), the CPU 20 of the digital portable telephone 3 generates operation determination data D13 corresponding to the operation contents (pushing operation) and transmits it to the notebook personal computer 2 via the radio interface for short distance 25.

[0075] At step SP8, when the CPU 10 of the notebook personal computer 2 receives the operation determination data D13 via the radio interface for short distance 16, it takes out the address data which is personal information, from the HDD 14, in accordance with the received operation determination data D13, opens the taken address data on the RAM 11 to display the address database on the HDD 14.

[0076] Then, the CPU 10 of the notebook personal computer 2 extracts only a record of the person names, from the taken address data, and transmits it as record data D14 to the digital portable telephone 3 via the radio interface for short distance 16.

[0077] At step SP9 when the CPU 20 of the digital portable telephone 3 receives the record data D14 via the radio interface for short distance 25, it marshals and displays the person names on the display 23 based on the received record data D14.

[0078] The CPU 20 of the digital portable telephone 3 scrolls the marshaled person names in accordance with the rotation operation of the jog dial 4 (FIG. 1) with the person names marshaled and displayed on the display 23.

[0079] When the user selects a desired person name of which the address he/her wants to know, with the selector 62 by the pushing operation, the CPU 20 of the digital portable telephone 3 generates selection data D15 corresponding to the person name being selected and transmits this to the notebook personal computer 2 via the radio interface for short distance 25.

[0080] At step SP10 when the CPU 10 of the notebook personal computer 2 receives the selection data D15 via the radio interface for short distance 16, it takes out address record data D16 corresponding to the received selection data D15 from the address database in the HDD 14, and then transmits it to the digital portable telephone 3 via the radio interface for short distance 16.

[0081] At step SP11 when the CPU 20 of the digital portable telephone 3 receives the address record data D16 via the radio interface for short distance 25, it displays the address based on the received address record data D16 on the display 23.

[0082] In this way, the digital portable telephone 3 receives the address record data D16, which is desired by the user, taken out from the HDD 14 of the notebook personal computer 2, via the radio interface for short distance 25, and visually displays this as an address on the display 23, thereby informing the user of the address of the desired person, without directly operating the notebook personal computer 2.

[0083] Therefore, the digital portable telephone 3 can function as a remote controller for remotely operating the notebook personal computer 2, by only pressing the remote control start key by the user.

[0084] (3) Operation and Effects of the Embodiment

[0085] According to the aforementioned configuration, in the information processing system 1, the digital portable telephone 3 receives function item information representing various functions of the notebook personal computer 2 which is to be operated, from the notebook personal computer 2, and displays a menu screen 60 based on the received function item information, thereby informing a user of the function item names representing the various functions of the notebook personal computer 2.

[0086] Thereby the user who operates the digital portable telephone 3 sees the menu screen 60 (the E-mail item 61B and the address item 61F) being displayed on the display 23 of the digital portable telephone 3, thus easily recognizing the functions of the notebook personal computer 2 which can be remotely operated.

[0087] The digital portable telephone 3 generates a processing command (operation data D11, select data D12, operation determination data D13, selection data D15) corresponding to a function item name determined according to user's input operation using the operation means (the jog dial 4), and directly transmits it to the notebook personal computer 2 via the radio interface for short distance 16.

[0088] The notebook personal computer 2 receives the processing command (the operation data D11, the select data D12, the operation determination data D13, the selection data D15), which is transmitted from the digital portable telephone 3, and executes predetermined processing (step SP6, step SP8, step SP10) corresponding to the processing command.

[0089] Thereby, the user does not directly operate the notebook personal computer 2, the digital telephone 3 can be used for remotely operating the notebook personal computer 2 while making the user recognize the operation state of the notebook personal computer 2, thus it can function as a remote controller of the notebook personal computer 2.

[0090] According to the aforementioned configuration, in the information processing system 1, the notebook personal computer 2 can be remotely operated with the digital portable telephone 3 without having a wired connection to each other, thus making it possible to significantly improve operability for users.

[0091] (4) Other embodiments

[0094] In this case, finally, the notebook personal computer 2 performs the same processing as the contents indicating the operation of the digital portable telephone 3, without performing processing associated with the contents representing the operation of the digital portable telephone 3. Therefore, the notebook personal computer 2 can prevent consumption power occurred when the associated processing is performed one by one.

[0095] Furthermore, in the aforementioned embodiment, the case has been described where the digital portable telephone 3 uses the CPU 20, the radio interface for short distance 25, and the antenna 31 as function item information receiving means to receive function item information (item data D10) representing functions of the notebook personal computer 2 to be operated, which is directly transmitted from the notebook personal computer 2.
